Observateur et contrôle optimal : améliorer l'efficacité de la conduite automobile avec Kalman et Pontryagin
2010
The PhD presents a combined approach to improving individual car efficiency. An optimal observer, the Extended Kalman Filter, is used to create an efficiency model for the car. Particular attention was paid to handling the asynchronous and redundant nature of the measurement data. A low-cost sensor suite developed to measure data is described. This sensor suite was installed on multiple vehicles to good success. It employsan accelerometer, gps, fuel injector timer, and Vss input to measure all the data necessary to reconstruct the car's state. This observer and sensor suite can be used as the base for any study which requires car efficiency maps, allowing research to proceed without manufac…
Temporal-range estimation of multiple objects: evidence for an early bottleneck.
2011
When making parallel time-to-contact (TTC) estimates of two approaching objects, the two respective TTC estimates interfere with one another in an asymmetric fashion. The TTC of the later-arriving object is systematically overestimated, while the estimated TTC for the first-arriving object is as accurate as in a condition presenting only a single object. This asymmetric interference points to a processing bottleneck that could be due to early (e.g., during the estimation of the TTC from the optic flow) or late (e.g., during the timing of the response or the motor execution) constraints in the TTC estimation process. We used a Sperling-like prediction-motion task to differentiate between the…

Does Learning Through Movement Improve Academic Performance in Primary Schoolchildren? A Systematic Review
2022
Physically active children have greater motor competence and a faster maturation compared with their sedentary peers. Recent research also suggests that physical activity during childhood may also promote cognitive development and therefore improve academic performance. The aim of this study was to understand if physically active academic lessons may improve academic achievement in primary schoolchildren. A systematic review following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted. The search was performed on the following database: PubMed, Web of Science, Scopus, Education Resources Information Center (ERIC), and PsycINFO (APA). Stu…
Extending existential feeling through sensory substitution
2023
AbstractIn current philosophy of mind, there is lively debate over whether emotions, moods, and other affects can extend to comprise elements beyond one’s organismic boundaries. At the same time, there has been growing interest in the nature and significance of so-called existential feelings, which, as the term suggests, are feelings of one’s overall being in the world. In this article, I bring these two strands of investigation together to ask: can the material underpinnings of existential feelings extend beyond one’s skull and skin? To begin, I introduce and adopt a componential-systemic view of extended affectivity. In doing so, I specify the vehicle externalist criteria for extension em…

Liikuntaintervention vaikutus 3-7-vuotiaiden lasten fyysiseen aktiivisuuteen ja motorisiin taitoihin sekä fyysisen aktiivisuuden yhteys sydän- ja ver…
2005
Sääkslahti selvitti väitöskirjatutkimuksessaan runsaaseen ulkoliikuntaan kannustavan liikuntaohjelman vaikutuksia 3-7-vuotiaiden lasten liikunnan määrään ja perustaitoihin. Lisäksi hän tarkasteli liikunnan määrän ja laadun yhteyttä sepelvaltimotaudin riskitekijöihin.Lapset tarvitsevat liikuntaa kasvaakseen ja kehittyäkseen. Hyvin pitkään oletettiin, että lapset liikkuvat ja leikkivät riittävästi. 1990-luvun aikana erilaiset tietotekniset laitteet ja pelit alkoivat kilpailla lasten huomiosta ja ajankäytöstä. Hyvin suuri osa lasten ns. vapaista leikeistä on aikaisemmin ollut erilaisia kasvua ja kehitystä tukevia liikuntaleikkejä. 2000-luvun alussa tilanne kuitenkin on muuttunut. Ajankäytön mu…
Do you like driving? A critical view on car advertising and its environmental rhetoric
2018
Sustainable development, as well as other narratives within the framework of environmental conservation, is often used as an advertising resource to improve a brand image. In this paper, a teaching proposal based on a critical analysis of the discourse of a set of television commercials is presented. Specific attention is given to the car industry, due to its huge environmental implications and its impact in mass media and popular culture. This study highlights that persuasive discourses around automobile still persist, which are more emotional than rational, as a way to elude the true debates about today's social and environmental challenges. El desarrollo sostenible, así como algunos otro…

Aplicación de la reprogramación neuromotriz a una técnica deportiva
2023
Este trabajo analizó los efectos de la práctica en variabilidad y de la reprogramación neuromotriz con el método Allyane sobre la percepción de autoeficacia y el rendimiento en el lanzamiento a canasta en baloncesto tanto en tarea cerrada (lanzamiento de tiro libre) como en tarea abierta (lanzamiento en partido). Se utilizó un diseño unifactorial intersujeto de 3 grupos con medida pre y postest con bloqueo aleatorio. La intervención se realizó en un equipo de baloncesto de l’Alqueria del Básquet, cadete femenino (14-15 años) de primera autonómica. 3 Jugadoras conformaron el grupo de entrenamiento en variabilidad y realizaron un trabajo de 15 sesiones de 20 minutos de lanzamiento a canasta c…
